We divide 77267 by 21
Our goal is to divide 77267 by 21.

Advancing to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 21

Let's proceed to step 2:
77 divided by 21 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 63 away from 77, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 21

Going ahead to step 3:
The number 21 fits into 142 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 126 from 142 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 21

On to step 4:
When dividing 166 by 21, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
If we subtract 147 from 166, we get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 21

Step 5:
If we divide 197 by 21, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3679.0
Deduct 189 from 197 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 6:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3679.3
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3679.38
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 3679.38
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3679.3809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3679.38095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3679.380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3679.3809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3679.38095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 3679.38095238 with a remaining 2e-09.
